PASTEURIZING APPARATUS-f Specification of Letters Patent. Application filed June 16,1906. Serial No. 322.010.

Patented May 14, 1907.

To mi] mimm/ it may concern:

Be it known that I, FRAXK-TYSON, a citizen of the United States, and a resident of Canton, Ohiofhave invented certain Improvements in Pasteurizing Apparatus, of

which the following is a specification.

My invention consists of certain improvements in thc pasteurizing apparatus forming the subject of my Letters Patent No. 804,687, dated November 14, 1905, the object of my present invention being to provide for the quick and effective cooling of the liquid after the heating of the same, and to facilitate the circulation of the water or other liquid. used for effecting the heating or cooling of the rotating plates over which the liquid to be pas-f teurized is caused to flow by tion. hereinafter set forth, reference being, had to the accompanying drawing, in which Figure 1 represents, in vertical section, pasteurizing apparatus constructed in accordance with my present invention, and Fig. 2 is an enlarged vertical section of part of the same.

centrifugal acvIn the apparatus forming the subject of.

my previous patent, before referred .to, the liquid to be pasteurized was fed onto the central portion of a rotating horizontal plate,

a and was caused to flow over the surface of said plate by centrifugal action, being finally discharged fromthe periphery of theplate into a suitable receiving trough, the liquid,

during suchi'lOW, being subjected to heat, .or

being cooled, by causing a flow of hot or cold water in contact with the opposite side of the plate.

In carrying out my present invention, I.

employ, in connection with the heating device, a plurality of cooling devices and I provide each of the devices with means for fa mounted and are connected by chain gearmg, or equivalent mechanism, so as to rotate in unison. I

Each treating plate operates in connection with a vessel 7, for containing water or other heating or cooling fluid, the plate serving as a These objects I attain in the manner '-and near the outer portion cap or cover for said vessel, and being provided with a curved peripheral flange 9, over which the liquid under treatment is discharged from the treating plate into an annul'ar trough 10 of the water vessel. each vessel alsdhaviiig, between its water chamber and said trough, .a supplementary vtromqdl or groove 11, into which projects a flange 12 on the. under side of the flange 9, whereby any water escaping over the rim of the vessel will be directed into said supplementary trimgh, and thereby prevented from gaining access to the trough .10 and mixing with the liquid under treatment. The three treating plates and the vessels co-opeiating therewith are' located in different horizontal planes, the permost plate constituting the heating dr vice, and the intermediate and lowern'i. plates serving as cooling devices.

sel 7 a spout '13 delivers thecontents of said trough to a feeding funnel 1 1 of the'interine diate cooling device, and from the trough 10 of the latter a spout 15 delivers the contents to a feeding funnel 16 of the finalcooling device, a spout 17 delivering from the trough -10 of the latter device into any suitable storing or transporting vessel.

Each of the plates 1, 2, and 3 has a backing plate 19, forming, with the top plate, a chamit I]; 5 From the trough 10 of the uppermost ves' her 20 for the reception andcirculation of the heating or cooling. liquid, this chamber being in communication, through a central hollow hub '21, with the liquid at andnear the central portion of the vessel 7, and being also "in communication, through openings or channels 22 in the back plate,

with the liquid at of said vessel 7, whereby the rotation of either treating plate will, by the operation" of centrifugal force, tend to cause circulation of the water or other fiuidthrough the chamber'20, as indicated by the arrows. In some cases, however, it is advisable to assist the centrifugal force in inducing .and maintaining such circulation,

and the provision of such aid to circulation constitutes one of the features of my invention.- In the uppermost or heating device of the series this aid is furnished by an inje ctor'operated by steam, hot water, air or other fluid,

preferablysteam, which, in addition to its primary purpose, also has the effect of main I taining the heat of'the flowing liquid by ad; mixture therewith of the steam, .hot water,

or other fluid, whereby the injector is operated. Such injector consists. in. the present instance, of n supply nozzle 23. and it comhining tube 24. with funnel end 25 into which the is projected, said jet inducing u, lion of Water from the vessel 7 into the combining tube, and the mixture of the voter and in- Cluoinglluid being delivered vertically from the upturned end or said combining tube into the hollow huh ol the hacking plate 1%) ol the treating plate 1, and again serving as r jet lo induce the lion or water lroni the Vessel 7 into the chamber 20.

In order to assist circ-ulniimi ol the '\\'fll0l in the chambers 20 o! the coo ng plates 2 and 3 the open huh oi the backing piutc l9 oi each of said cooling plates is pro cided at the bottom with inclined blades or vanes 26. Whose tendency, when-the plate is rotated, is to cause an. up\ fl-1K] llow oi water through i re hollow huh from the vessel 7 into the chum- 'he1'20. In either case, the water thus caused to enter the chamber 20 in the center. linds its Way hack to the Vessel 7 through i he openings or channels 22 -idjnccnt lo ihe periphery ol the plates. By the use of :1 plurality or cooling devices I 1111 ennhl d (U employ, in the second oi said devices, :1 tooling lluid having it tempemture iowcr than that employed in the prinuiry cooling device, thus effecting a gradual cooling oi the liquid under treatment, and permitting or the rapid llon' ol said liquid over each ol the cooiing plates.
